Every Medicare beneficiary with a prescription drug benefit carries a Part D plan, and every Part D plan has a reimbursement right under the Medicare Secondary Payer Act when drug costs were paid because of a covered injury. The practical problem is that most plaintiff attorneys address Part A and Part B conditional payments through CMS's BCRC process but treat Part D as an afterthought, not realizing that the Part D plan sponsor has an independent right of recovery with its own legal framework, its own reporting requirements, and its own double-damages exposure under the MSP statute.
Overlooking Part D at settlement creates post-disbursement exposure. A Part D plan that was not notified and not paid retains its right of action against both the beneficiary and the settling party, and the double-damages provision under 42 U.S.C. § 1395y(b)(3)(A) allows private plans to recover twice the amount improperly retained. For background on the broader framework for Medicare and lien resolution in PI settlements, our ongoing coverage addresses conditional payment disputes, MSA obligations, and Medicaid coordination.
The Legal Framework for Part D Recovery
Part D drug plans are administered by private plan sponsors under contracts with CMS. Despite being privately administered, they are subject to the Medicare Secondary Payer Act, meaning that when an injury-related drug cost is properly attributable to a tortfeasor's negligence, the Part D plan that paid for that drug has a claim against the settlement proceeds. This is true whether the plan is a standalone Prescription Drug Plan (PDP) or a Medicare Advantage plan with integrated Part D coverage (MA-PD).
CMS does not centrally administer Part D conditional payment recovery the way it administers Part A and Part B through the BCRC and MSPRC contractors. Each Part D plan sponsor manages its own recovery claims independently. There is no single CMS portal where you can look up and resolve all Part D claims the way you can submit the BCRC proof-of-representation package and receive a conditional payment letter for Part A/B. This decentralization is what causes the problem in practice: attorneys who know the BCRC process assume all Medicare recovery is handled there, and it is not.
Identifying the Part D Plan
The first step is identifying whether your client has a Part D plan and which sponsor administers it. This can be done by reviewing the client's Medicare Summary Notice for Part D entries; asking the client for their prescription drug insurance card; or submitting a query to the BCRC in the proof-of-representation package and requesting information about Part D enrollment alongside the Part A/B conditional payment analysis. The BCRC will confirm Part D enrollment status, though it will not provide the Part D claim details themselves.
Once the plan sponsor is identified, submit a formal notice of representation to the plan's MSP Recovery department. Major Part D plan sponsors including UnitedHealthcare, CVS Caremark, Humana, Express Scripts/Cigna, and Aetna all have dedicated MSP recovery teams that process these claims. Smaller regional plans may route recovery requests through their general compliance office. The formal notice starts the clock on the plan's obligation to provide a claim listing and recovery demand.
What Part D Covers and What It Doesn't
Part D covers prescription drugs paid by the plan that are reasonably related to the claimed injury. In a significant auto or workplace injury case, this commonly includes prescription analgesics, muscle relaxants, anti-inflammatory medications, psychiatric medications prescribed for injury-related anxiety or depression, and prescription sleep aids. It does not include over-the-counter medications even if prescribed, and it does not include medications for pre-existing unrelated conditions even if those conditions required new prescriptions during the same treatment period.
Getting the plan to narrow its claim to injury-related prescriptions requires submitting medical records showing the treatment chronology and the prescription indication for each drug at issue. Plans routinely start with an overbroad claim that includes every prescription filled during the injury period; the medical records submission is the mechanism to reduce that to the injury-related subset.
Negotiating and Resolving the Part D Claim
Part D recovery amounts are generally smaller than Part A/B conditional payment claims because drug costs, while significant, are typically dwarfed by hospitalization and surgical costs in serious injury cases. However, in catastrophic injury cases with extended treatment courses, Part D claims for months of pain management, psychiatric medications, and specialty drugs can reach five-figure amounts that materially affect the client's net recovery.
The same proportionate reduction argument that applies to Part A/B applies to Part D: if the settlement represents less than full compensation for the injury, the plan's recovery should be reduced proportionately. Document the allocation between economic and non-economic damages, the basis for any reduction in settlement value, and the attorney's fee and cost deduction, then present that analysis to the plan's recovery department as the basis for a compromise demand. Most plans will accept a reasonable compromise rather than litigate, particularly for amounts under $50,000.
One key difference from Part A/B: the common fund doctrine does not automatically apply to Part D plan recovery the way it can apply to government-administered Medicare claims. Whether the plan bears a proportionate share of attorney's fees depends on the plan's contract language and applicable state law. For recent case law on MSP double-damages claims and common fund doctrine, tracking the federal circuit court decisions that have addressed private right of action suits by Part D plans directly affects the leverage available in Part D reduction negotiations.
